Hi.

Create Object A (a action logging class)
Create Object B (a class which allows generates logging actions).

As each method in B is called a log entry is made by using an IN and OUT method on A.

During the shutdown, the __destroy method of A is called (which closes the log), then, the __destroy method of B is called. This method has the logging code in it. This then tries to call a destroyed object.

As you cannot refer to an object until it is created, you should always destroy objects in the reverse order in which they were created.

Richard.

Reproduce code:
---------------
<?php
class A
	{
	public function __construct()
		{
		echo 'Constructing A<br />';
		}

	public function __destruct()
		{
		echo 'Destroying A<br />';
		}

	public function Logging($sLog)
		{
		echo date('r') . ' '. $sLog . '<br />';
		}
	}

class B
	{
	public function __construct()
		{
		$GLOBALS['objLogger']->Logging(__METHOD__ . ' ' . __FILE__ . ' ' . __LINE__);
		}

	public function __destruct()
		{
		$GLOBALS['objLogger']->Logging(__METHOD__ . ' ' . __FILE__ . ' ' . __LINE__);
		}

	public function Action()
		{
		$GLOBALS['objLogger']->Logging(__METHOD__ . ' ' . __FILE__ . ' ' . __LINE__);
		}
	}

$objLogger = new A();
$objAction = new B();
$objAction->Action();
?>

Expected result:
----------------
